Narrated `Aisha: (the wife of the Prophet) Allah's Apostle used to pray (at night) in Ramadan.

Narrated `Aisha: Allah's Apostle used to pray in his room at night. As the wall of the room was LOW, the people saw him and some of them stood up to follow him in the prayer. In the morning they spread the news. The following night the Prophet stood for the prayer and the people followed him. This went on for two or three nights. Thereupon Allah's Apostle did not stand for the prayer the following night, and did not come out. In the morning, the people asked him about it. He replied, that he way afraid that the night prayer might become compulsory.

Narrated Aisha: Once in the middle of the night Allah's Apostle (p.b.u.h) went out and prayed in the mosque and some men prayed with him. The next morning the people spoke about it and so more people gathered and prayed with him (in the second night). They circulated the news in the morning, and so, on the third night the number of people increased greatly. Allah's Apostle (p.b.u.h) came out and they prayed behind him. On the fourth night the mosque was overwhelmed by the people till it could not accommodate them. Allah's Apostle came out only for the Fajr prayer and when he finished the prayer, he faced the people and recited "Tashah-hud" (I testify that none has the right to be worshipped but Allah and that Muhammad is His Apostle), and then said, "Amma ba'du. Verily your presence (in the mosque at night) was not hidden from me, but I was afraid that this prayer (Prayer of Tahajjud) might be made compulsory and you might not be able to carry it out."

Narrated `Aisha the mother of the faithful believers: One night Allah's Apostle offered the prayer in the Mosque and the people followed him. The next night he also offered the prayer and too many people gathered. On the third and the fourth nights more people gathered, but Allah's Apostle did not come out to them. In the morning he said, "I saw what you were doing and nothing but the fear that it (i.e. the prayer) might be enjoined on you, stopped me from coming to you." And that happened in the month of Ramadan.

Narrated 'Urwa: That he was informed by `Aisha, "Allah's Apostle went out in the middle of the night and prayed in the mosque and some men prayed behind him. In the morning, the people spoke about it and then a large number of them gathered and prayed behind him (on the second night). In the next morning the people again talked about it and on the third night the mosque was full with a large number of people. Allah's Apostle came out and the people prayed behind him. On the fourth night the Mosque was overwhelmed with people and could not accommodate them, but the Prophet came out (only) for the morning prayer. When the morning prayer was finished he recited Tashah-hud and (addressing the people) said, "Amma ba'du, your presence was not hidden from me but I was afraid lest the night prayer (Qiyam) should be enjoined on you and you might not be able to carry it on." So, Allah's Apostle died and the situation remained like that (i.e. people prayed individually). "
